I am a mother of 4 boys - ages 11, 9, 5 and just turned 1 year old. I have experienced A LOT in all these years when it comes to sleeping. I will be honest with you - you are teaching your baby what is called a "sleep association" and she will continue to need that paci until you teach her to sleep without it. Now - I shouldn't say that is the case for 100% of babies, but it's a very good chance that she will. All of us need something to sleep well (a sleep association) - whether it's a certain type of pillow, a blanket, etc... If you rolled over in the middle of the night and found that your pillow or blanket was missing, you would wake right up and not be able to or sleep until you had it back under your head or pulled back over your body. Babies are no different. If they fall asleep with a paci in their mouth, what do you think will happen if they wake up a little bit and it's not there? They will freak out until it's back where they want it. If she learns to sleep without it, she will get a much better sleep and so will you and she will not NEED it in the middle of the night. I know there are a lot of moms who shudder at hearing the name "Dr. Ferber", but I'm telling you, his book saved my life. It is the most educational book out there on sleep habits. He has actually done the studies so his book is not just based on OPINIONS. I highly recommend reading his book. You will not regret it. I know it's a tough situation - I've been there! Good luck!
